QCA8084 is four-port PHY with maximum link capability 2.5G, which supports the interface mode qusgmii and sgmii mode, there are two PCSs available to connected with ethernet port. QCA8084 can work in switch mode or PHY mode. For switch mode, both PCS0 and PCS1 work on sgmii mode. For PHY mode, PCS1 works on qusgmii mode, the last port (the fourth port) works on sgmii mode. Besides this PHY driver patches, the PCS driver is also needed to bring up the qca8084 device, which mainly configurs PCS and clocks. Changes in v3: 1. pick the two patches to introduce the interface mode 10g-qxgmii from Vladimir Oltean(olteanv@xxxxxxxxx). 2. add the function phydev_id_is_qca808x to identify the PHY qca8081 and qca8084. 3. update the interface mode name PHY_INTERFACE_MODE_QUSGMII to PHY_INTERFACE_MODE_10G_QXGMII.
